Washing and drying machine

Abstract

A washing and drying machine has an object to improve a drying efficiency of a laundry and reduce a drying time, and includes an outer drum; an inner drum rotated in this outer drum and having a substantially cylindrical shape to constitute a storage chamber therein; a takeout port which is constituted in one end surface of a cylinder of this inner drum in an axial direction and via which the laundry is to be taken or introduced; a plurality of through holes which are formed around a side surface of the cylinder of the inner drum and in the other end surface of the cylinder in the axial direction and from which water is discharged during the washing and through which circulation air for drying circulates during the drying; and a blowing regulation unit which blows the air for drying into the storage chamber from the side of one end or the other end of the cylinder of the inner drum in the axial direction and which allows the air to flow from the through holes on the other end side or from the one end side and which inhibits outflow of the air for drying from the other through holes.

Description

technical field [0001] The present invention relates to a washing and drying machine having a storage room for storing laundry, and washing and drying the laundry in the storage room. Background technique [0002] In recent years, there has been provided a washing and drying machine that automatically performs washing to drying in a storage room for storing laundry. The washing and drying machine is provided with a cylindrical inner drum in a cylindrical outer drum capable of storing water, and a plurality of through holes through which air and water can circulate are formed on the inner drum. The inside of the layer drum is a storage room for storing laundry. The cylinder shaft of the inner layer drum is connected to the shaft of the drive motor attached to the main body, and is held rotatably in the outer layer drum around the shaft. [0003] And when the laundry and the detergent corresponding to the amount of the laundry are put into the storage chamber, when the power...

Problems solved by technology

[0007] In such an existing washing and drying machine, although the air in the storage room is discharged from a plurality of through holes formed on the inner drum during the drying operation, the through holes are formed on the inner drum as a whole as described above. There are multiple, so the heated air discharged from the air outlet to the storage room is easy to flow out of the storage room from the through holes formed around the side of the inner drum

Moreover, since most of the air will not return to the storage chamber again, but will be discharged from the suction port to the outside of the outer drum, it is impossible to fully contact the laundry in the storage chamber with the heated air.

As a result, it takes a long time until the laundry is dried, and the energy consumption for drying the laundry increases, resulting in a problem of high energy costs such as electricity bills.
